  Embodiments of a cleaning device according to the present invention will be described below with reference to the drawings.

  1 and 2 show Example 1 of a bag cleaning apparatus according to the present invention, FIG. 1 shows the front surface thereof, and FIG. 2 shows the left side surface thereof.

  The cleaning device according to the present invention is composed of several parts around an air nozzle placed substantially at the center of one bottom plate 1, and is integrated into one unit as a whole. The air sucked by the blower motor 2 installed on the bottom plate 1 passes through the air ejection pipe 3 and is ejected upward from the air ejection port 4. In addition, from the inlet 5 that opens in an annular shape so as to surround the air outlet 4, the air flows downward and flows into the chamber 6 provided at the lower portion, and further passes through the exhaust pipe 7 to be exhausted. It flows into the dust bag 9 attached to 8.

  Further, struts 10 are erected on both the left and right sides of the bottom plate 1, and the left and right struts 10 support a top plate 11 that extends in the horizontal direction so as to block the upper side of the air ejection port 4. The length of the column 10 can be adjusted, and the distance a between the inflow opening 5 and the top plate 11 opened in an annular shape is slightly shorter than the length in the vertical direction when the flexible container is fully expanded. Adjust to a small amount.

  Hereinafter, a cleaning method will be described using the cleaning device configured as described above.

  The worker puts the outlet of the flexible container after the contents of powder etc. are discharged into the inlet 5 so as to cover the outlet 4, and the air blown from the outlet 4 flows into the flexible container. Then, the flexible container is expanded so as to be lifted upward by the air pressure, and is in an inverted state supported by the top plate 11 as shown in FIGS. At this time, the outlet 13 of the flexible container only needs to be inserted into the inlet 5 so as to cover the air outlet 4 from above, and no fixing means is used. Note that if the surface of the top plate 11 that comes into contact with the expanded flexible container is concave, the contact with the flexible container that is expanded and has a convex surface may be stabilized.

  When the flexible container is in an inverted state as shown in FIGS. 1 and 2, the air ejected from the air ejection port 4 becomes an upward flow 14 toward the bottom of the flexible container 12 supported by the top plate 11. Then, a downward flow 15 is formed along the side wall of the flexible container 12 toward the flexible container mouth and flows into the inlet 5.

  In this state, the operator strikes the wall surface of the flexible container 12 with bare hands or using an appropriate tool. By so doing, residues such as dust attached to the inner wall surface of the flexible container 12 can be knocked down and placed on the downward flow 15 in the flexible container.

  The air that flows in from the inflow port 5 flows into the chamber 6, the flow velocity thereof decreases, and a part of the residue such as dust accumulates here. The inflowing air changes its direction of flow, passes through the exhaust pipe 7 and flows into the dust bag 9, and the remainder of dust and the like is collected in the dust bag and only the purified air is collected. It flows through the dust bag.

  In the first embodiment described above, all the components are placed on the bottom plate 1 to form one unit, but it is not always necessary to combine them into one unit. In Example 1, indoor air is sucked by a blower motor and discharged into the room, but both or one of them may be outdoor or outdoor. Further, a blower motor may be provided on the exhaust side to forcibly form a discharge flow.

  Example 2 of the apparatus for cleaning the inside of the bag according to the present invention is the same as Example 1 except for the configuration of the top plate. Therefore, the top plate will be described below.

  FIG. 3 shows a top plate and its mounting state in the second embodiment. The top plate of Example 2 is circular or substantially circular, and the surface that contacts the flexible container is concave, and is supported rotatably on the arm 16 by the central shaft 17. With this configuration, the operator can easily rotate the inflated flexible container supported by the top plate. There is an advantage that it can be easily performed without interference.

  Moreover, if the diameter of the top plate is made smaller than the bottom surface of the flexible container, there is an advantage that it is possible to perform an operation in which a worker strikes a part of the bottom surface to remove dust and the like.

  In Example 3 of the apparatus for cleaning the inside of the bag according to the present invention, the planar shape of the top plate in Example 2 is a star shape. There is an advantage that the dust can be removed by hitting the wall surface of the flexible container to be supported from between the elongated fingers of the star shape. The shape of the top plate of the third embodiment is not limited to a star shape, and may be an elongated finger shape.

  The present invention can be used for cleaning various bag bodies including a flexible container bag.
